Small-Scale Biogas Technology

Biogas technology has been used globally for decades, with primary applications for large-scale, high-tech commercial systems in Europe (and limited penetration in the US) and small-scale, low-tech “house-hold” scale systems in Asia. The potential for application of biogas technology on small-scale farms in the US is great for providing alternative means for managing on-farm organic wastes (manure, on-farm food processing) and providing a clean, renewable source of energy for on-farm applications (thermal energy for water heating, food processing, etc.). Making biogas technology a viable option for small farms requires the development of reliable, effective biogas reactors that can be readily fabricated and maintained by farmers. With support from the USDA Western Sustainable Agriculture Research & Education Program (Western SARE), CSANR developed a project to explore options for developing improved biogas technology for applications in small-farm settings in the US. Resources developed in this project are available on this site.
